Agglomerated SSL was written in order to hide the OpenSSL API. It strives to reuse the OpenSSL APIs and provide a much simpler and more sane interface for programmers that are interested in writing applications that require the SSL/TLS protocol for secure communications.

Avian is a lightweight virtual machine and class
library, both written from scratch to provide a
useful subset of Java's features. It's well-suited
to cross-platform applications which need a
typesafe language but must remain small and
self-contained.

Bitcoinproof creates a forgery-proof timestamp for your data, secured by the Bitcoin network. It allows you to prove that a certain event happened before a certain point in time. Maybe you want to prove that the damage in your flat already existed when you moved in, or that you were in possession of a great artwork before it was published, proving you are the author.

Conseptizer is two things: 1. a closure(-mimic) / higher-order programming and dynamic typing library for the C programming language, 2. a very dynamic programming language that provides expressiveness through simplicity and offers powerful features that cannot be found in mainstream languages today. Each of these two aspects can be useful on their own, but the combination and tight integration in Conseptizer means: if at some point your runtime performance requirements are not fulfilled by the dynamic language, it is very easy to migrate parts of your program code to C.

CryptSharp provides a number of password crypt algorithms: BCrypt, MD5 (and Apache's htpasswd variant), PHPass (WordPress, phpBB, Drupal), SHA256, SHA512, and Traditional and Extended DES. It also includes Blowfish, SCrypt, and PBKDF2 for any HMAC (.NET's built-in PBKDF2 implementation supports only SHA-1). If you are looking to store passwords, odds are CryptSharp will have the algorithm you want.

DisPass is a passphrase generator that generates unique passphrases formed from a master password and a label, helping you get rid of the bad habit of using a single password for multiple Web sites. It is a console application, but it also has a simple graphical interface.

ENet for C# wraps the C-language ENet networking library. For games and other realtime applications, if you use TCP, old data can hold up newer data, even if it is no longer relevant (old positions, etc.). Your players will perceive any lost packet as a "lag burst". ENet supports multiple in-order streams of data, and allows you to decide on reliability on a per-packet basis. The library is useful for both client-server and peer-to-peer architectures.

Hnefatafl is an implementation of the Norse board game. Hnefatafl 11x11, 13x13, Tablut, and many other variants are supported using rulesets. There is a command-line interface and an X interface (the latter is optional).
